Problems solved by technology

Especially for the creation of the BIM model of the sprinkler system, because the sprinkler system is spread throughout the building, the pipeline is complex, the number of components (including pipes, sprinklers, connectors) is large, and the diameter of the pipeline is variable, the traditional manual creation of the sprinkler system is difficult. BIM models are particularly time-consuming and labor-intensive

Embodiment 1

[0034] refer to figure 1 , a method for automatic modeling of a sprinkler system based on Revit, including the following steps:

[0035] S1, link CAD drawings: link the CAD drawings of the sprinkler system to the Revit project and save them, read the DWG files based on the Teigha.NET, for. storage;

[0036] S2, pipeline generation: Obtain the required floor elevation, pipeline type, system type and pipeline offset in the Revit project, as well as the pipeline line and pipe diameter annotation information extracted from the DWG file, based on the Revit API secondary development tool through Identify the two endpoints of the pipeline line to generate the corresponding pipeline;

[0037] S3, sprinkler generation: Add the family instance of the sprinkler in the project file, obtain the information of the floor elevation, sprinkler family type and sprinkler offset, and the sprinkler block information extracted from the DWG file, and generate the corresponding based on the Revit A...

Abstract

The invention discloses a method and a system for automatic modeling of a spraying system based on Revit. The method comprises the following steps: S1, linking CAD drawings; the CAD drawing of the spraying system is linked to a Revit project to be stored; the method is based on Tega.NET. Reading the DWG file by a form.dwg class library, and writing the DWG file into the form.dwg class library; thedrawing information is disassembled into pipeline lines, pipe diameter marks and nozzle blocks for classified storage; according to the method, the data of the spraying system in the CAD drawing is automatically read, the spraying system BIM model completely conforming to the CAD drawing is automatically generated, meanwhile, the function of rapidly modifying the model under the condition that the spraying system collides with other professional models is provided, and the engineering quantity of various components of the spraying system can be accurately counted.

Description

technical field [0001] The invention relates to the technical field of models, in particular to a method and system for automatic modeling of a sprinkler system based on Revit. Background technique [0002] BIM technology is another revolution in the construction industry after CAD, and it is of great value to the entire construction industry. At present, when most domestic designers create BIM models, they mainly carry out manual modeling based on two-dimensional CAD drawings, which involves a lot of tedious and repetitive work. Especially for the creation of the BIM model of the sprinkler system, because the sprinkler system is spread throughout the building, the pipeline is complex, the number of components (including pipes, sprinklers, connectors) is large, and the diameter of the pipeline is variable, the traditional manual creation of the sprinkler system is difficult. BIM models are particularly time-consuming and labor-intensive. In addition, when the sprinkler sys...
